Once Is Enough

ONCE IS ENOUGHBy Pirisi, Angela — Publication Date: Sep/Oct 2000

Summary: Focuses on studies which found that the hormone prolactin may dampen sexual arousal after orgasm which may be signaling to the body that it has had enough. Details on how the study was carried out; Link of prolactin to functions in both men and women; Other findings.

You may want to make love all night long, but your body most likely doesn’t, new studies show.

Studies at two German universities found that the hormone prolactin may dampen sexual arousal after orgasm, perhaps signaling to the body that it’s had enough. Researchers, led by Michael Exton, Ph.D., a biological psychologist at the University of Essen’s Institute of Medical Psychology, asked 10 women to masturbate until achieving orgasm, then examined them afterward. He discovered a surge in the hormones adrenaline, nonadrenaline and prolactin that occurred during arousal and orgasm—but prolactin’s rise was the most dramatic and prolonged.

Prolactin has been linked to functions in both men and women, including sperm and breast milk production. Exton believes it regulates dopamine, a neurotransmitter that plays a role in movement control, pleasure and pain, and likens it to a built-in switch for turning on and off sexual desire. “The prolactin surge may possibly signal the brain and reproductive organs that ‘once is enough,’” he says.

Women are not alone in releasing prolactin after orgasm—Exton’s previous research on men and animals has uncovered a similar dynamic. He believes that because women seem more capable of having multiple orgasms than men, prolactin response to sexual arousal may vary individually, a theory that begs further research.

So it’s prolactin that makes me wonder about whats in the fridge or what’s on TV or that I maybe can get a few hours sleep before getting up.

In 2003, on the 50th anniversary of the historic ascent, an occasion marked by banquets and other festivities, Sir Edmund recalled: “After the expedition, Tenzing and I spent quite a lot of time together, but we never, ever, talked about the climb up Everest. I don’t know why. We talked about our families; talked about the world and its problems; talked about just about everything. But we never ever once talked about Everest.”
